Actually I just used the example that provided with the kit, this example used to run the NuTiny as a mouse or keyboard. So I uploaded to code by using the programmer/ debugger that located on the right side of the kit and its uploaded successfully but, when I moved the USB cable to the left side HID J1 that connected to the ARM chip it doesn't shows any response even the power LED indicator doesn't power up ?!

Is it work fine if I desoldered the shown resistor (actually I think it's not a resistor, it's just a jumper because i checked it shows 0 ohm), and then solder a jumper instead so I can easily change between 5V and 3.3V ?!?

But what about the programming voltage? I mean when I want to upload a program to the target "NUC140VE3AN" I have to select 3.3V only and after that change to 5V ?! or I can directly programming it via 5V?

Yes, you can directly programming it via 5V.
